T0 aZZ whom it may concern.'

Be it known that l, Gnnconr KovALn- Yrrci-r, a subject of the Emperor of Russia, residing at South Portland, in the county of Multnomah .and State of Gregori, have invented'new and useful. improvements in Ships, or' which'theollowing is a specificai tion. I

My invention relates to safety devices for ships, or means to prevent the. sinking of ships in case of injury causing leakage at sea. r

The object of my invention is' to produce the hull of a ship constructed 'of separable sections adapted to be disunited to permit the leaking lower or keel section to be severed from the upper or superposed section and sink without carrying down the upper or superposed section.

i A further object of my invention is 'to produce means for automatically closing the openings in the bottom of the upper section 'which communicate with thelower section before the lower section is released, and for severing the smoke funnel above the lower section. l

Another objest thereof is to produce means for tightly uniting the upper and lower sections of vthe ship and for quickly and conveniently separating the sections when the lower section is filled with water to permit the lower section to sink from the upper section, and a still further object of my invention is 'to produce amore simple and efiicient device of said character than has her' toiore been attained.

To these ends, myinvention includes the combination and arrangement ofcomponent parts to be hereinafter described and more particularly pointed out in the claims.

ln the accompanying drawings, in which like reference characters indicate similar parts, Figure l "is a side view ofthehull oi my ship showing theA separable sections united; Fig. 2 is a transverse sectional View or the same Fig. 3 is a longitudinal sectional 4view showing the apparatus for operating the means for removably securing the upper section to the lower section and the apparatus for..4 severing the smoke stack and openings in the bottom of the upper section in normal position; Fig. 4C is a similar view showing said apparatus as actuated to release the lower section to sii lnseverthe smoke stack and close the openings thev secured by r llleitented c't. i914.

upper section; Fig. 5 is a transverse scctional View of my ship taken on the line 5--15 of Fig. 3; Fig. 6 is a similar viejv taken onthe line 6*-6 of Fig. 3, and Fig. 7 is a kdetail View of the latches for holding the' sections of my ship united. Fig. 8 is a detail of the A.mechanism for severing the smoke sta-ck.

Referring now to the drawings, l indicates the lower or keel section of the hull of my ship and 2 designates the upper or superposed section. T he two sections are fitted together around their outer edges by a water-tight tongue and groove joint 3, and the lower section secured upon the upper section by a plurality of upright stays 5 ernbracing the sides of the upper section and elcasa-ble latches 6 on the. upper section to hereinafter described.

The driving' ngifachinery of the ship, if it be a; power driven vessel, may preferably be carried in the lower section l, and the upper section 2 provided with a bottom 7 having abat-cli 8 therein to communicate with the lower section, and with one or more "ttoropenings 8 to admit the supply of i'resh air to the lower section.

The upper ends of the uprights 5, as be- :t'ore stated, are held on the upper section by the releasable latches, which preferably comprise the pivoted members 40 over one end of which the ends of the uprights are looped, while the opposite ends of the pivcted members are held down by the pawls 9 pivoted at one end on the pivoted arms l0, and -the free ends 9 bear upon the free ends of the pivoted members i0 and engage the notches 7 therein. The upper or free ends of the pivoted arms l0 are conneotcd bythe rods ll and il." on 'the oppositev sides of the vessel. Said rods ere'connected at one end with tie levers and l2 .by the links 18 and 13', and the levers may its release to save the superposed section, I

the levers l2 and 12 may be thrown, as shown in Fig. 4c of the drawings, which releases tlie pawls 9 from Contact with the free ends of the pivoted members 40 and releases the uprights 5 to drop and the lower sec` tion to sink from beneath the upper section. rlhe smoke stack e, may be made ofgtwo iointed sections,

and passes through. the,

' tion 1 of the hull, is carried the hollow shaft 14C in which is loosely carried the float 14. The lower end of the shaft is open to permitthe ingress of water. The float 14 is connected by the stem 14 with the lever 15 which ispivoted intermediate its ends 'at 15', and which is adapted at its opposite end to normally support the pivoted weight 16. Said weight is pivotally suspended upon the frame of the lower section, and is connected with the pivoted lever 17 at one end while the opposite end is connected with -the sectional smoke stack 4, and is adapted when the float is elevated in the shaft, and the weight 16 is released as Shown in Fig. 4, to sever the sections of the stack.

For the purpose f of communicating fresh air through the ventilator opening 8,- I provide the flue 18 passing vertically through the upper section and discharging into the lower section. For the further purpose of automatically closing the ventilator port 8, I provide the trap door 20 pivoted beneath the bottom of the upper section and adapted to normally swing downwardly. Said trap-door may be automatically closed by the counter-weighted bell-crank lever 21, the unweighted ond of which is adapted to bear upon the'lower face of the trap. ySaid lever is fulcrumed at 21 on the outer face of the bottom of the upper section 2, and is normally held in open position shown in Fig. 3 of the drawings by the latch 22 on the end of the ivoted lever 22, which enages the weiglited end of the lever 21. aid lever is operated to release the latch by the float 23 to which it is attached, and which oat is loosely carried in the hollow shaft 24. Said oat is so positioned that it will not be actuated to operate the lever until the water in the hold has risen higher than was required to elfect the separation of the smoke stack.

As shown in the drawings, the upper face of the trap-door 2O is provided with an upright stud 25 having a notched head 25 adapted to be engaged by thepawls 26 car ried on the transverse bar 27 which is pivh oted at one end on one side ofthe port while the opposite end is engaged by the end 28 .of the pivoted and weighted lever 28. Said lever 28 is normally held upright by the frame 29 to which it is latched' at its I upper end, but when the trap is closed as before described, the latch is released and the weighted end 28*1 is released to drop downwardly and exert a lifting pressurel the door is closed, strikes and raises the latch 36 which holds the weighted lever 37 inactive, and the under face thereof is notched at v35 to be engaged by the lifting end of the lever 37 to tightly close the door upon the bottom of the upper section and prevent leakage through the hatch.

Having thus described my invention, what I claim as new, and desire to be secured by Letters Patent, is

1. The hull of a ship, comprising separable upper and lower sections, means for removably securing said sections together, a bottom for the upper section having openings therein communicating with the lower section, water-tight closures for said open` ings, and means actuated by the rise of water in the lower section for voperating' said closures.

2. In a sectional hull for ships, the combination with a keel section, of a superposed section separably mounted thereon and jointed thereto, a bottom for the superposed section having an opening therein, a trapdoor for closing said opening, a weighted le ver for closing said door, a latch for nor- .mally holding said lever inactive, a Hoat carried in the keel section and connected with said latch adapted to be actuated by the rise of water therein to trip the latch and release said weighted lever to close the trap-door, substantially as described 3. In a sectional hull for ships, the combination with a keel section, of a superposed section separably mounted thereon andI jointed thereto, a bottom for the superposed section having an opening therein communieating with the lower sectionpa hinged door for closing said opening, a. weighted leverl for closing said door, a latch for ,normally holding said lever inactive, a ,float 'carried in the keel section and connected\j\vith saidV Y v rac latch adapted to vloe actuated bythe 'rise of water therein to trip the latch and release..`

said weighted lever to close. the 'dpqr,; a-

latch for locking said door shi-1t, a pivoted lever for pressing the door-tightly closed to. =v`v form a Water-tight closure, and a latch for normally holding said last mentioned lever inactive and adapted to be tripped by the closing 'of the door to release the lever, sub` I stantially as described.

4l. In a sectional hull for ships, the Vcombi-A nation with ay keel section, of a superposed section separably mounted thereon, a bottom for the super-posed section having en opening therein, a sectional smoke funnel passing through said opening, a pivoted weight mounted on the lower section and cenneetecl et one end to the lower section of the funnel, n, latch for normally holding said weight elevated, a float carried on seid lower section and connected Wit-l1 said latch adapted to be actuated by the rise of water in the lower section to operate the latch to release said pivoted Weight to disconnect the sections of the funnehsubstentally as described.
